A hand-held noninvasive component of an ultrasound imaging assembly designed to be moved over the intact surface of a patient's body, typically with a coupling gel, during a variety of extracorporeal ultrasound imaging procedures (non-dedicated). Sometimes referred to as an ultrasound probe, it converts electric voltages into ultrasound which it transmits, detects resulting echoes, and transmits a proportional signal/data to an ultrasound system controller for image processing and display. This is a reusable device.
